Japan

In forceApproach: Innovation-first framework law; light-touch and non-punitive

Japan passed the AI Promotion Act in May 2025, taking an innovation-first path that is lighter than the EU. The law sets principles and lets the government issue guidance and, in serious cases, name companies, but it avoids heavy penalties. The emphasis is on encouraging adoption and coordination rather than prescriptive rules, with existing privacy and sector law filling the gaps.

Key points

  • The AI Promotion Act was approved by Japan's parliament on May 28, 2025.
  • It is principle-based and non-punitive, favoring guidance over fines.
  • The government can investigate and publicize serious problems, which functions as reputational pressure.
  • Existing personal-information and sector laws continue to apply to AI.
